Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in several processes, including heart development; mesenchymal cell development; and regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including circulatory system development; negative regulation of SMAD protein signal transduction; and regulation of DNA-templated transcription. Located in cytoplasm and nucleus. Is expressed in several structures, including early conceptus; genitourinary system; heart; hindbrain; and sensory organ. Used to study dilated cardiomyopathy. Human ortholog(s) of this gene implicated in atrial heart septal defect; atrial heart septal defect 4; congenital heart disease; tetralogy of Fallot; and ventricular septal defect. Orthologous to human TBX20 (T-box transcription factor 20). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
